EH2-M – 2″ (50mm) High Pressure Metallic AOD Pump

Sandpiper high-pressure AOD pump is a 2:1 ratio high-pressure pump powered via compressed air. This series of 2″ (50mm) positive displacement pump is capable of delivering discharge pressures twice the inlet pressures up to 250 psig (17.2 barg), the EH-2 M high pressure AOD pump is designed for durability. The metallic diaphragm pump can be utilized in demanding applications, such as filter press feeds, as well as other critical applications requiring higher discharge pressures most air-operated diaphragm (AOD) pumps aren’t capable of achieving. 

The Sandpiper metallic ball valve pump is engineered to include weighted check balls and metallic seats to help ensure a robust and durable valve seal for performance in high-pressure applications. Unlike other high-pressure pumps on the market, the SANDPIPER EH2-M unit features a balanced diaphragm design. This design allows for a minimal pressure differential across the diaphragm, helping to decrease the need for replacement parts – effectively decreasing downtime and, ultimately, lowering the total cost of ownership. The high-pressure pump is available in cast iron and stainless steel with various diaphragm (elastomer) options.
